embedtest Cannot find module

Details

I compiled node.js from source code with vcbuild.bat on windows os. no problem. then i tried to compile with visual studio 2022. no problem. I tried to run the release version of Embedtest from the Visual Studio 2022 compilation, following the comments instructions in the embedtest.cc file. // Format of the arguments of this binary: // Building snapshot: // embedtest js_code_to_eval arg1 arg2... // --embedder-snapshot-blob blob-path // --embedder-snapshot-create // [--embedder-snapshot-as-file] // [--without-code-cache] // Running snapshot: // embedtest --embedder-snapshot-blob blob-path // [--embedder-snapshot-as-file] // arg1 arg2... // Snapshot number: // embedtest arg1 arg2... always fails with error: Cannot find module
